Definitions
- the present invention relates to a tobacco extract containing tobacco terpenes and a method for producing the same, and more particularly to a tobacco extract containing sesquiterpene or diterpene and a method for producing the same.
- the aroma components of tobacco leaves are aromas mainly composed of decomposition products derived from pigments generated at the time of maturation or in the drying process, that is, carotenoid decomposition products such as ionone and megastigmatrienone, and leaf surface resin components such as sesquiterpene and diterpene. Most of these aroma components are hydrophobic.
- various extraction methods have been studied. For example, many examples using liquefied carbon dioxide gas or supercritical carbon dioxide gas have been studied by taking advantage of the characteristics of a target component (PTLs 1 and 2).
- raw materials expanded with liquefied carbon dioxide gas have been studied as one of the raw materials for cigarettes, and the process is very similar to the extraction process using carbon dioxide gas described above.
- PTL 3 discloses an apparatus including: an extraction container that brings carbon dioxide in a supercritical state into contact with a tobacco raw material to dissolve a tobacco component in the carbon dioxide; a separation container that is connected to the extraction container and separates and recovers a fat-soluble ingredient of the tobacco component from the tobacco component dissolved in the carbon dioxide; a circulation path that circulates the carbon dioxide in a supercritical state between the extraction container and an absorption container that stores pure water while purifying the carbon dioxide with a purification layer made of activated carbon, and absorbs a water-soluble portion of the tobacco component in the pure water; and a recovery container that recovers pure water having absorbed the water-soluble portion of the tobacco component from the absorption container as absorption water.
- PTL 4 discloses a method in which a tobacco component contained in vaporized carbon dioxide that is exhausted by heating after impregnating a tobacco raw material with liquefied carbon dioxide is heated from 150°C to 400°C to obtain heated aroma. This method is very unique in that reductone is obtained. However, it is suggested that even unnecessary components derived from heating, as shown in PTL 5 and the like, may be generated.
- an object of the present invention is to provide a method for efficiently producing a component useful as a flavoring agent from a raw material derived from tobacco by a simple method.
- the inventors have found that the above problem can be solved by using, as a raw material, a waste including tobacco stem or a solid extract discharged simultaneously with separation of carbon dioxide gas in the expansion treatment of tobacco. That is, the above problem is solved by the following present invention.
- a method for producing a tobacco extract containing a tobacco terpene including:

- the production method of the present invention includes the following processes:
- a raw material derived from tobacco is prepared.
- the raw material derived from tobacco is a raw material derived from plants of the genus Tobacco. Examples thereof include tobacco raw materials such as tobacco leaves, aged tobacco leaves, shredded tobacco, or tobacco powder, and processed products or wastes obtained by subjecting the tobacco raw materials to processing.
- the tobacco leaves are a generic term for harvested tobacco leaves that have not undergone aging.
- One embodiment of aging includes curing.
- the shredded tobacco is obtained by shredding aged tobacco leaves or the like into a predetermined size.
- the tobacco powder is obtained by pulverizing tobacco leaves or the like.
- the expansion treatment refers to a treatment of impregnating a tobacco raw material with a liquid and rapidly vaporizing the liquid to increase the bulk of the tobacco material (see FIG. 16 ).
- a discharged solid discharged by a known expansion treatment can be used.
- the tobacco raw material is a tobacco leaf, a shredded tobacco, or a tobacco powder.
- the discharged solid obtained from the expansion treatment using supercritical carbon dioxide contains a large amount of tobacco terpenes.
- the tobacco terpenes are preferably sesquiterpene or diterpene (hereinafter, also simply referred to as "terpenes").
- the expansion treatment process includes a process of threshing and shredding tobacco leaves as a raw material at the initial stage, tobacco fine powder and stems as a small amount of waste shreds are mixed into the tobacco raw material.
- the raw material is subjected to an expansion treatment, after the expansion, light expanded shreds, heavy stems, and non-expanded shreds are discharged together with carbon dioxide gas, and become discharged solids.
- the discharged solids are the above-described solid fat-soluble ingredients, or solids of expanded shreds, stems, and non-expanded shreds, or mixtures thereof accordingly.
- the discharged solid is used as a raw material derived from tobacco will be described as an example.
- the discharged solid is subjected to solid-liquid extraction with an aprotic solvent.
- the aprotic solvent is a solvent that is hardly soluble in water and can form an organic phase separated from an aqueous phase because it does not have a proton to be dissociated.
- Examples of the aprotic solvent include esters such as ethyl acetate, butyl butyrate, and ethyl butyrate; halogenated hydrocarbons such as dichloromethane and chloroform; ketones such as acetone; nitriles such as acetonitrile; and hydrocarbons such as hexane.
- an aprotic medium-polar solvent containing a hetero element, such as an ester or a halogenated hydrocarbon is preferable from the viewpoint of efficiently extracting target terpenes.

Therefore, as the solvent, ethyl acetate, butyl butyrate, ethyl butyrate, dichloromethane, and chloroform are preferable, ethyl acetate, butyl butyrate, and ethyl butyrate are more preferable, and ethyl acetate is still more preferable.
- the target terpenes are transferred to the aprotic solvent (organic phase).
- the aprotic solvent can be classified into low-polar solvents and medium-polar solvents depending on their polarity.
- the aprotic medium-polar solvent is defined as a solvent exhibiting a positive value of log Kow of 2 or less

- the discharged solid may be subjected to extraction with an aprotic solvent and water or an acid aqueous solution.
- nicotine in the discharged solid can be transferred to the aqueous phase by water.
- the water preferably contains an acid, that is, the water is preferably an acid aqueous solution.
- an inorganic acid or an organic acid can be used, but sulfuric acid, citric acid, or oxalic acid is preferable from the viewpoint of stability of the nicotine salt and the like.
- the pH of the acid aqueous solution is preferably 4 or less, and more preferably 3 or less.
- the lower limit of the pH is not limited, but is preferably 2 or more.
- the temperature at which this process is carried out is not limited, but is preferably 10 to 35°C, and more preferably 20 to 30°C. In this process, it is preferable that the discharged solid be subjected to solid-liquid extraction with an aprotic solvent, and then the organic phase be subjected to liquid-liquid extraction with the water or acid aqueous solution. In the solid-liquid extraction, an insoluble solid content may be removed by filtration or the like.
- the organic phase obtained in the process 2 is recovered.
- the organic phase is the organic phase obtained by the solid-liquid extraction or the organic phase obtained by the liquid-liquid extraction.
- the recovery method is not limited, and can be performed using, for example, a separatory funnel. If necessary, the aqueous phase may be washed with an aprotic solvent, and the washed solvent may be added to the organic phase. In this way, a solution of a tobacco extract containing terpenes can be obtained.
- the aprotic solvent is removed from the organic phase to obtain the extract.
- the method for removing the solvent is not limited, and for example, an evaporator can be used.
- a protic polar solvent or an aprotic medium-polar solvent is added to the extract to precipitate or disperse a solid content.
- the protic solvent is an organic solvent having a dissociable proton, and examples thereof include aliphatic alcohols such as methanol, ethanol, and propanol; glycols such as propylene glycol; and ketones such as acetone.
- the aprotic medium-polar solvent used in this process examples include aromatic alcohols such as benzyl alcohol, phenylethyl alcohol, and cumyl alcohol; esters such as ethyl acetate; ethers such as diethyl ether; and chlorinated hydrocarbons such as chloroform.

- the aprotic medium-polar solvent used in the process 4 is preferably an aromatic alcohol.
- the protic polar solvent (preferably, aliphatic alcohol) phase obtained in this process contains target terpenes.

- the protic polar solvent phase preferably does not contain components having an RI of more than 2,500 and 3,500 or less. This is because the components having an RI of more than 2,500 and 3,500 or less are mainly higher hydrocarbons, and produce an undesirable smoking flavor when heated to 160 to 250°C.
- RI is an index obtained by standardizing the retention time of gas chromatography using a standard substance.
- RI refers to an index obtained by a linear method using the retention time of n-paraffin as a scale.
- the aprotic medium-polar solvent (preferably, aromatic alcohol) phase obtained in this process contains target terpenes. Since the terpenes have an RI of 1,600 to 2,500, the aprotic medium-polar solvent phase contains components having an RI of 1,600 to 2,500. Further, the aprotic medium-polar solvent phase preferably contains components having an RI of more than 2,500 and 3,500 or less, that is, contains components having an RI of 1,600 to 3,500. The components having an RI of more than 2,500 and 3,500 or less are nonpolar, dissolve aroma components better, and have a function as a retention agent. Therefore, when the components are heated to 220 to 280°C, the flavor components are volatilized to give soft and smooth smoking flavor. Accordingly, the tobacco extract obtained using the solvent is suitable for a tobacco flavor inhalation article heated to 220 to 280°C, and more suitable for a tobacco flavor inhalation article heated to higher than 250°C and 280°C or lower.
- the protic polar solvent is preferably ethanol, and the aprotic medium-polar solvent is benzyl alcohol from the viewpoint of imparting excellent smoking flavor, safety, and the like.

In the latter embodiment, it is preferable to further promote the precipitation of the solid content.
- the precipitation method or the method for promoting precipitation is not limited, and examples thereof include allowing the system to stand and centrifuging.
- the temperature of the system is preferably -10 to 10°C. Setting such a temperature prevents the target terpenes from deteriorating.
